      Explanation: Recorded from 2024 March 10, to 2025 March 1, this   
      composited series of images reveals a pattern in the seasonal drift of   
      the Sun's daily motion through planet Earth's sky. Known to some as an   
      analemma, the figure-eight curve was captured in exposures taken on the   
      indicated dates only at 18:38 UTC from the exact same location south of   
      Stephenville, Texas. The Sun's position on the 2024 solstice dates of   
      June 20 and December 21 would be at the top and bottom of the curve and   
      correspond to the astronomical beginning of summer and winter in the   
      north. Points that lie along the curve half-way between the solstices   
      would mark the equinoxes. The 2024 equinox on September 22, and in 2025   
      the equinox on March 20 (today) are the start of northern fall and   
      spring. And since one of the exposures was made on 2024 April 8 from   
      the Stephenville location at 18:38:40 UTC, this analemma project also   
      reveals the solar corona in planet Earth's sky during a total solar   
      eclipse.
